Protecting Sight #138: How to lead in a crisis. Intumescent cataract decompression, pterygiums, and SLT vs. drops on visual field progression. Leonardo and the mechanical arts.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, short story or significant work.

Here’s today’s list:

1. Ted Talk – Amy C. Edmondson: How to lead in a crisis. “Humility, transparency and urgency are the keys to successfully steering an organization — big or small — through the challenges that come your way. Leadership expert Amy C. Edmondson provides clear advice and examples to help any leader rise to the occasion.” (

Love the 4-minute Ted Talks. High yield pearls and insights.

2A. Cataract Surgery – Uday Devgan MD – Cataract Quiz: intumescent decompression. Well done.

2B. Cataract Surgery – Dr. Ameen Marashi – Cataract & Pterygium (Facebook). Nice case.

3. Journal – Visual Field Outcomes from the Multicenter, Randomized Controlled Laser in Glaucoma and Ocular Hypertension Trial (LiGHT). Wright D, Konstantakopoulou E, Montesano G, et al. Ophthalmology, October 2020.

Selective Laser Trabeculoplasty (SLT) continues to show its value.

4. Book Chapter – Leonardo da Vinci by Walter Isaacson. Chapter 12, “The Mechanical Arts.”

Each chapter is filled with Isaacson’s masterful insights on Leonardo da Vinci’s life.
